Current as of 4/12/2019
Affected devices:
- TP-Link RE450 (all versions)
- TP-Link RE400 (all versions)
- TP-Link RE355 (all versions)
- TP-Link RE350K (all version)
- Spectrum Askey RAC2V1K
*Note: TP-Link at this time is not aware of any other affected models. However, if you feel you have a model that is affected please contact us at ussupportteam@tp-link.com so we can help research our model.
Symptoms: The range extender will connect to the router, devices will connect to the RE, and they will be assigned a correct IP address (192.168.x.x) however, they will not be able to access the internet or communicate with the gateway address of the Spectrum router.
Cause: Internal testing has revealed the cause is the current firmware in the Spectrum router (version 1.1.16)
Possible Solutions: Currently we are working with Spectrum to fix the issue. In the mean time we suggest one of the following solutions:
- Request Spectrum to downgrade your router’s firmware to the previous version (1.0.16)
- Request a replacement router from Spectrum. We have confirmed the following models are not affected
- Segemcom RAC2V1S
- Netgear 6300

- Assign IP address to your client device manually (Static IP) *consult your device manual
- Make the range extender your DHCP server (See Below)
Making your Range Extender your network’s DHCP Server:
Step 1: Disable the DHCP Server of your Spectrum router
Step 2: Seth the RE450 to a static IP address with in the router’s subnet
Step 3: Enable DHCP Server on the RE450
Step 4: Change the Gateway and DNS settings. Both the Gateway and DNS servers must be the Router’s IP address. Example: 192.168.1.1
